Server Requirements

Interspire Email Marketer is a web-based application that requires a server with the following minimum requirements:

  • Linux (Debian / Ubuntu is preferred)
  • Nginx 1.18.x or above / Apache 2.4.x or above (nginx is preferred)
  • PHP 8.3 or 8.4 (8.4 is preferred). Full PHP 8.4 support was added in v8.7.5 .
  • MySQL 8.0+ / MariaDB 10.x (MariaDB is preferred)
  • To use autoresponders and triggers your need cron on your web server.
  • To process bounced emails using an IMAP account, the PHP IMAP extension is no longer required (handled by the bundled webklex/php-imap library). v8.7.5 To process bounces using a POP3 account, your version of PHP still needs the IMAP extension (ext-imap, the imap_xxx functions) installed. If ext-imap is unavailable, use an IMAP bounce account instead.

Please download and run check_iem.php to help verify that the system requirements are met before starting the installation. Once you have verified the requirements, follow the simple instructions outlined in the Installation Guide.

We also provide step-by-step installation guides for VPS environments running Ubuntu or servers with cPanel, making setup quick and straightforward
